Each paper clip can be traded for three matches. each pencil can be traded for six paper clips. two pencils and two paper clips are worth (more than, less than, or equal to) thirty-eight matches.

Paperclip = 3 matches

Pencil = 6 paperclips

22×3 = 66

66×3 = 198

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
